1. When you're riding your bike down a hill at such speeds that when you peddle it seems as though your chain has fallen off.
me," That hill was off the chain logan!" Logan," Yea man, I was in top gear, and still couldn't peddle faster."

A way stupid people who think they're hip describe an awesome event, such as a party or concert. Often used by crackheads or Asians who think they're down with black folk.
Crackhead/Asian: Yo nigga, that party last night wuz off the chain, muthafucka!
Black dude/normal person: Shut the fuck up. (Beats his ass). Don't ever say that again.
